What does the Identifier setting indicate about a field?

• A. Indicates whether the field is indexed by its data type.
• B. Indicates if the field is the workspace's unique identifier with a value of yes or no.
• C. Indicates whether the field is visible in the viewer.
• D. Indicates whether the field is open to associations.

Answer: (B)

The Identifier setting shows whether a field serves as the workspace’s unique identifier. When it is set to Yes, that field acts as the primary key for records in the workspace, meaning each item must have a distinct value in that field and it’s used to reliably reference and link items. If it’s set to No, the field is just a regular attribute with no role as the unique key. In most cases, there is a single field designated as the Identifier to ensure a consistent way to distinguish every item.
